Mikey's Beast SSSG OSCILLATOR

[BroMikey]

I have changed the circuit again slightly. See if you can
tell where it is changed. The hint is look for the 8 pin
latching relay.

Today I charged a 12v battery hooking it up and leaving
then later when I came back I found that the relay and LED
had also discharged my battery a tiny portion on the
crowbar side.

I have added two pins on my latching relay so i can shut
both sides off, not just one side.

See what I mean?

@ BroMikey
This is my alternative crowbar circuit, the transistor is BC547 / BC182 and zener is 500mW details are open to experiment and a gate resistor can be included to suit device in use. two switch positioned shown for 15.2v and 12.7v

Okay Dupe I reworked it for a 2n2222 and used 75 ohms at the
positive input terminal. Very cool running zener and stable latch.

I like the sound of the relay and I did not use a diode, but will.

thanks for the new circuit. It works very well.

Your very welcome Mikey, well done. By the way just waiting a delivery of Alum to convert some of my batteries! Cheers Dupe

Hey Dupe

Alum is the ticket for many batteries above 70 degree temperatures.

I have freshen up your circuit diagram with MY 2N2222 addition

If you have any other alternative circuits, please let me know.

Alternative circuits may turn out to be the main circuit.

I have not decided what the difference is yet other than the cap

increases holding time as well as stabilizing incoming energy so

the SCR does not trigger from minor fluctuation.



I have learned that the Bedini oscillator gives a surge of power

when starting the circuit and is enough to set off the

circuit over-voltage showdown.


Also when use with high energy capacitive discharging devices.

Use the surge limiter found in the diagram's.

[BroMikey]

Just had a thought about your spikes!! you can get transient suppression diodes ................................[/url]

Oh yeah almost forgot to tell you something DUPE.

I was beating up this one set of oscillator components and didn't
realize I had some kind of leakage problems that was causing
strange things. As soon as I dumped the old parts and put a new
set on a broad everything went normal.

So my Led is not cracked open on .5v anymore.

These oscillators are strange indeed.

I've had a few experiments with similar oscillators. One was on the toroidal core, the frequency was 2MHz.
It requires some really fast diodes.

Yes these oscillator circuits can create some hefty transient switching spikes rich in harmonics. Board layout also effects circuit stability, and a significant influence on other components and adjoining circuitry also. Adequate filtering and decoupling is important, anyway this project of yours is really coming together Mikey.

[Dupe]

Good point... Ultra fast switching diodes should be used for all HF applications with these and similar circuits.

Thanks guys

Does anyone have anything to add??.. let me know I like new circuits.

I was really in shock when I dumped those clunky old slow diodes

for some fast diodes. Dem babies can really blow your doors off.

I think it almost doubled on the output.

This is the one I am working on this week. So far as of last night
I successfully switched 2 of the 3 stages as the voltage climbs.
The third stage tonight.

What that means is that as the battery charges up to 26 volts a
relay drops a resistor to lower input power to the OSCILLATOR in
GENMODE. One drops at 28 volts and at 31volts turns off so this
circuit will be updated for 24volt operation to all who use 24v.


It looks like the old air core Bedini Oscillator just aint gonna cut it
so I will change out the wire to get a better power output. The
one I had already uses 4 channels MJL21194 130foot coil of 22awg
chokes at 2 amps.

It was an old experiment that was targeted for under 1 amp. It is
highly efficient for cleaning up tiny batteries but I already have
that in 3 other units so this one will get upgraded to faster
diodes and more powerful transistors. Plus 6 strands of 20awg
wire. I want to try 3 strands per 200watt transistor and fast
diodes in this one.

I am using 75-90 foot Litzed coils that will produce over 300 volts
in seconds unlike the beginners model I built that can't get much
over 100 volts in a while.

A good length can be anywhere from 40 feet up to 300 feet
depending on what you want to do. In my case the energizers
need only high voltage radiant for occasional battery plate
clean up and GENMODE for current pulses.

I have found that the best trade off is to increase wire diameter
of shorten the coil length of 22awh and 20awg to increase
power production without forcing an over heating condition
through so much resistance.

Don't get me wrong, the super long thin wire has it's place say
running at 50ma off a solar panel out back very very efficient.
Scaling up to charge a 1000ah should be done with many many
strands of 20awg or use 14awg for fewer strands.

Personally I am getting to like 20awg wire because 6 strands
going to a single high powered transistor has more circular
mill diameter and produces radiant much more easily.

I will soon post more pictures of my tiny little brain storm.
I look at the circuit and think how much time I have put into
it and it is so small, hardly seems significant.

But it is significant to keep the oscillators/energizers from
burning up in all circumstances.

[BroMikey]

One more thing about dropping resistors at 26volts and 28volts
and running a low powered long duration charge up to 31+ volts.
If you don't get this part of Energizing a battery then your battery
bank will not set at 13.2volts.

If your battery is setting at 13volts after a charge you are charging
to quickly and probably with to much power.

If you don't learn this, you won't understand why your battery
life is so short. My batteries have been run for so long the right
way that they are getting higher and higher.

My huge batteries sit at 13.5 volts now after 1 year of properly
handling them.

Thanks for listening.

Here are a few pictures posted on my website.

The long thin relay that is the largest is the latching relay.

All values will be posted some time in the future for this

24volt energizer and control board. The only diagram I have

so far is the one above maybe 2 posts back that has 3 channels.

That diagram is incomplete.

I have shown circuits that generally work and not testing is

underway.

Hi Dupe

I have a statement and a question for you.As I have
been building these control boards I find that your suggestion
to use 1 percent resistors is a good idea on the gates of the SCR's.

However one thing I am noticing (I am still using MY crowbar)
is that as I increase or decrease charging input current this
slightly changes the resistance level trigger.

For an example (Not that I need to yet) if I go from 2 amps
on the input all of the way down to 200ma I see a non linear
response.

QUESTION

As you put it before that it is a good idea to stabilize the gates
of the SCR's do you think that the voltage divider and zener
on your circuit will keep this from happening?

Okay again I am eventually going to make a more versatile
Energizer for experimental use that will go from 100ma all the
way up to 2 amps so I need to see my crowbars respond the same
at all amp input levels.

Do you think the circuit using the divider will keep my voltage
setting based on resistance for the gate closer to the same
at all inputs?

I can clarify further if you did not understand my statements.

I will try it soon in the next circuits. For now my 2 amp scooter
charger works okay because all of my amp levels
are planned out for each crowbar.

Either way I will have to try your circuit using the divider and zener
as it seems a to be the next best idea

Mikey PS i think your circuit is gonna bee a lifesaver, DUPE

[Dupe]

Hi Mikey, My circuit is based on monitoring the voltage as seen on the battery being charged i.e. 12v / 24v etc. Preventing an over voltage situation occurring. I kind of understand what you are saying... you need to control your charging current at predetermined levels you select? In which case say you want to charge at 2amps and no more or no less then your charge ideally needs to be a constant current source. To an extent depends on what method you are using to charge your cells of course! Dupe

[Dupe]

Mikey are you currently using your SSG board 3 charger. I notice this shows a 14v run battery how have you configured it?
